but now we're lucky enough to have someone pay for them. there is a large tour of volcanic rocks a bit because toe factory the company builds up to sorties towards a day our own seventeen thousand have been sold so far each comes with us of books rose trained ses the device can be used in many regions and countries if we want to have as many people to be coming to bring you us to be able to record what we're doing in various parts of the country we don't want to on that if we're again remains here. uganda has a population of fourteen million ninety percent could chuckle so these are huge potential market for they told the benefits will also be huge and help to secure that for a station of the african continent. it's an old habit that spying more and more new uses it as an alternative to burning charcoal which is harmful to

both the environment and the people that are using it but now sharon will take you to not africa to tunisia to be precise. that's right i went there has come up with a clever business idea to use the waste from dates production by telling it to wonderful. accessories it's a way of reducing trash even if this trash is a gothic. community. isn't after the fruit of tunisia's date palms. instead she collects fallen leaves seeds and branches. for her it's not waste it's material for her artwork.

exactly the children that you saw waving at the end of the last field. otherwise we want to provide a healthy environment for and that can only happen if we walk together to stop climate change the us president might still buy it but what's leftist will tell you that global warming is real and it's a serious problem both for the environment and for us this short public service announcement explains why. that's how much average surface temperature has risen since eight hundred eighty. we burn too much fossil fuel drive too much and fly too much. as temperatures rise glaciers retreat columbia glacier in alaska is melting

especially fast losing as much as thirty meters a day. it's not only glaciers that have been melting over the past thirty years half of the ice in the arctic has disappeared. with devastating consequences less and less solar radiation is being reflected back into space. as a result that to speeds up global warming in the oceans as well. with a rise in water temperatures comes a rise in sea levels the results are especially dangerous for low lying coastal regions where much of the world's population lives. fast growing megacities are at risk kids for example the pudong district in the chinese city of shanghai in one thousand nine hundred was mainly farmland now it's

a finance and high tech hub and home to over five million people. entire island states such as the maldives are at risk of being swallowed by the sea. rising sea levels could make climate refugees of more than half a billion people worldwide. coastal flooding can destroy farmland by making it too salty deserts growing not only because of rising temperatures they are all seen used to be the fourth largest lake in the world until water was diverted for irrigation now it's almost completely dried up in africa over grazing in the sun hell has destroyed much of the soil the region subsistence farmers are struggling to survive. with. more than a fertile land surface is desert and many deserts continue to grow. ever

more forests are being cleared every three seconds one hundred trees lost that's the rate at which deforestation has been going on in the amazon for the past forty years yes that's right one hundred trees felled or burned every three seconds. like here in the brazilian state of around donia rain forest is cleared to make way for sowing fields cattle farms dams and reservoirs. the destruction of rain forests means even more c o two is released into the atmosphere and the earth gets ever warmer. and now we're going to meet professor. the director general and c.e.o. off the nigerian meteorological agency for years he has been collecting and

interpreting data about changing weather patterns in nigeria the country is currently struggling with extreme weather from he tweets to torrential floods is it caused by global warming and who is responsible. let's with him in the nigerian capital. let's just get the situation. situation how would you describe it's awful we have been having event. as to how. much it was to. take in the indication that turns on the long normal life of the country is causing. climate change. is melting that heat in the south and in

the equatoria. generally indoor what tends to happen here now is the global warming that is so much destruction. just. so much of this to see if.
