kew is the world leader in developing plant science. preparing for their mission to discover new species. and it is from here that this expedition will be launched. i have come here to see the expedition leader, doctor mauricio de bernardos. he works in a library for lab specimens. this is where we identify new plants. we believe we have more than 200,000 different species here. you are a botanist and a biologist. and a scientist and an explorer in some sense. what are you expecting to get from this mission? the most remote areas are the best preserved and this is going to be our most important expedition. we're going to try to get into the heart of this area. we do not know what we expect to find. what is at stake with this whole trip that we're doing? why is this so important? we are in a race against time to protect this biodiversity from disappearing. we have rapid deforestation. we see how we are losing this forest very quickly and ourjob is to get an understanding about the diversity of these resources as well as their importance.

carol kirkwood, you are at kew gardens this morning.ered is, when should you water your plant and how frequently to keep them as beautiful as they are here at kew gardens? the answer is minimise wastage and there are lots of things you can do to do that. the first thing is, probably watering first thing is, probably watering first thing in the morning and last thing at night, and that minimises evaporation and run. and there are little things like putting it into pots and you can upcycle water bottles to drip feed the pots and this minimises wastage.” bottles to drip feed the pots and this minimises wastage. i would have thought in this weather and heat you would have to water your plants every night, especially your tabs, but that is not the case. overwatering plans is one of the easiest ways to kill them. we need to water when the plants needed and we need to water the plants are not the soil. —— tubs. there are many ways to test out, look at the plant, is it wilting? test the soil, is it to dry underneath? test the compost in your po

over the internet, with greta in stockholm, while i am in a jewel of biodiversity, a glasshouse at kewtells me she hopes coronavirus will change the way the world approaches the climate challenge. it shows that, during a crisis, you act, and you act with necessary force. it feels like the corona crisis has sort of changed the role of science in our societies, that we are suddenly starting to understand that, "oh, yeah, we actually have to listen to the experts. that's actually something we depend on.". she has been following the black lives matter movement, and sees an important link between action on climate and action on other issues, including racism. it is always the fight forjustice. and it feels like we have passed some sort of social tipping point where people are starting to realise we cannot keep looking away from these things. we cannot keep sweeping these things under the carpet, these injustices. greta has made a radio programme during lockdown about her life as a campaigner. my message is, and has always been: listen to the science. she says the growing appetite for protes
