it's a very bleak picture for a lot of americans out there of white supremacy in fact all of our patients you're putting more money into the hands of some workers taking money out of the hands of other workers and everyone goes to their camp he becomes a us versus them this is the deal about constraining your nuclear program the bottom line the big questions on out is they are. the u.s. president's pledge at a world summit to cut emissions by 50 percent within 9 years the climate change activist is not impressed. you will still get away with continue to contribute to the destruction of presence and future living conditions. that we look at the battle by a biologist to save mankind for us from the ravages of the developments in brazil.

around the clock this is out 0 life and also coming up. my son had a smile that was worth a $1000000.00. yes the funeral for a 20 year old shot by a police officer in the same u.s. city where george floyd was killed. violence flares between palestinians and israelis and watched bodies to reach them during the holy month of ramadan. so it could be the world's moment of peril or a moment of opportunity the dramatic declaration from joe biden as he pledges the u.s. will be a global leader on climate change the president's kicked off a virtual summit on earth day by committing to an ambitious reduction in carbon emissions but critics are dismissing his plans as costly and ineffective white

house correspondent can we help it because i have a virtual global summit convened by u.s. president joe biden and an invitation to world leaders to combat climate change collectively the signs are on mistakes the science is undeniable and the cost of inaction is keeps mounting united states is awaiting where resolving to take action. biden announced the u.s. would cut fossil fuel emissions by up to 52 percent by 2030 the earth day pledge renews america's commitment following 4 years of inaction by predecessor donald trump it more than doubles america's target under the 2015 paris climate agreement that trump withdrew from and that biden rejoined when he took office. 40 world leaders participated including american adversaries russia and china china

is the world's biggest emitter of greenhouse gases president xi jinping pledged to achieve carbon neutrality by $26.00 to adding this jab at the united states china has committed to move from carbon peak to carbon neutrality in a much shorter time span than what might take many countries just weeks after the u.s. and russia leveled sanctions against one another ask elating tensions russian leader vladimir putin said he takes international commitments seriously like hero and paris hinting the united states does not russia st used its greenhouse gas emissions to a greater extent than many other countries but biden faces domestic challenges implementing his green economy or oil gas and chemical companies spent more than 100000000 dollars last year lobbying u.s. lawmakers to keep fossil fuel vehicles on the road speaking virtually before

a congressional panel swedish climate activists gratitude and berg to hold lawmakers accountable if they don't change i don't believe for a 2nd that you will actually do this because i'm a crisis doesn't exist in the public debate today and since it doesn't really exist and the general level of awareness is so absurdly low you will still get away with continuing to contribute to the destruction of presence and future living conditions. president biden's announcement of a new u.s. goal for reducing greenhouse gas emissions is ambitious but what it lacked are specifics including a legislative plan a budget or any kind of proposal for meeting biden's new climate target kimberley health al-jazeera the white house they want as wells as the author of the uninhabitable earth an editor at large at new york magazine he says many now

believe adapting to carbon neutral systems is a more lucrative option it's an incredibly ambitious target even if we totally zeroed out our emissions from the power sector we will be able to get there and then we have to cut from transportation infrastructure industry agriculture i think these are very tough targets to hit and without a sort of concrete plan for how to get there i'm skeptical nevertheless i think it's an incredibly lot of a step forward for the country that has produced the lion's share of the world's stark emissions to say that this is a very serious issue we need to be moving immediately and trying to take a retake a leadership position on the issue that they've abandoned at the pass i think there's a growing economic consensus all around the world that in fact the cost is negative that countries will be better off faster a move and i think that's why we've seen so many new ambitious pledges being made over the last year from the e.u. from south korea from japan and especially from china these are not pledges that were made on the occasion of the summit they were not pledges that were made in the

context of international negotiation they were made because these countries are a short term benefit in decarbonising i think the us is the same logic which means look to holistically we will be better off the faster move on climate of slower remove that will. well joy both in our the brazilian president told the summit the brazil will reach its goals on climate you try to achieve by 205010 years earlier than expected the president says efforts will be boosted by ending illegal deforestation which is sort of a 12 year high under his government environmentalist skeptical with some taking matters into their own hands i want to hear reports now from richard or. it has been a long and lonely walk for the past 22 years biologist madhu muska 30 has been patrolling the shores of rio de janeiro's polluted one about a bay clearing layers of trash trapped in the mud then planting millions of mangrove seeds one by one fabio are usually has been working with him from the

start. when real arrived here this was a dump we've been planning an average of 40000 seeds every week now we have an entire forest was cut there lee and his team have recovered 1300000 square kilometers of mangrove forest people have lent to 130 football stadiums the size of rio. now he's working on filling another patch of dirty black mud the same size with this powerful green vegetation he hopes the mangroves will help diminish the effects of deforestation in the amazon in march more than 800 square kilometers of the rain forest were destroyed more than double the amount in the same month last year yelling mangroves afford times the capacity to absorb and carbon dioxide and the amazon rain forest and the seas continue to rise with global warming they will

be our last line of defense. but mangroves protecting brazil's coast from north to south are in danger not from fire but from rampant urban development and the lack of basic sanitation it's a problem faced by poor and rich neighborhoods alike as we could see on a boat ride behind this exclusive condo in baja that usually. we're surrounded by nature and one of rio's richest neighborhoods but this group transparent water here is dangerous it's full of bacteria from untreated sewage which can cause liver cancer. its fishing season here all year round and not the kind that attracts tourists. a black river carrying trash from the sprawling city slums flows into the lake where so far is floating. 5 years ago rio de janeiro promised to clean it sacked for the olympic games but not much was done don't you folks but

there's more than enough money to take out of them violent what brazil lacks the political will for a long term plan that would benefit nature as well of economy but it must last at least 20 years and cannot be changed every time a new government of elected it took muska $32.00 decades to grow a mangrove forest almost all on his own he still hopes the results will convince others to follow his crusade monica an i.q. of al-jazeera rio de janeiro the funerals been held for don't deride the 20 year old black american shot dead by police during a traffic stop emotions run high coming just 2 days in a few kilometers from where a police officer was found guilty of murdering george for it 100 has more now from minneapolis in a warning there are some disturbing images his report. to the family. dante to meet you is right it's become an all too familiar american scene

group is that they have seen videos posted on social media of young palestinian men attacking jewish people filming it putting it on social media and since those videos have been posted we have seen sporadic. more more standardized now going over on the palestinian side of this protest people scattering once again and so this is where most of the. clashes between in the skirmishes between palestinians and the security forces have been going on in the sort of amphitheater area just down there with the smoke is in front of the damascus gate as i say that's been going on to one level or another for some days now the difference with this night is that they have been confronted here by jewish anti arab groups and then the security forces have been trying to separate them with some mixed success with there have been injuries that have been these ongoing clashes throughout the evening. still ahead here on al-jazeera we join ukraine's navy as
