A Quote by Leonardo DiCaprio
As a young boy, I was obsessed with endangered species and the extinct species that men killed off. Biology was the subject in school that I was incredibly passionate about.

For millions of years, on average, one species became extinct every century.... We are now heaving more than a thousand different species of animals and plants off the planet every year.
In fact perhaps the only law in biology is that all flesh is mortal and all species become extinct eventually.
The Endangered Species Act is the strongest and most effective tool we have to repair the environmental harm that is causing a species to decline.
A species may eat a particular bacterium, phytoplankton, smaller fish, or plant in an area. Lacking a predator, these species/populations will overgrow and alter the area's biology, overwhelming and driving to extinction dozens or hundreds or thousands of other local species.
We have a very old conservation movement, particularly in the United States, which has focused on campaigns to protect endangered species: the spotted owl, the old-growth forest. But usually it stops there. To me, biodiversity is the full spectrum. Species conservation is not only about wilderness conservation. It?s also about protecting the livelihood of people even while changing the dominant relationship that humans have had with other species. In India, it?s an economic issue, not just an ecological one.
Biology is a science of three dimensions. The first is the study of each species across all levels of biological organization, molecule to cell to organism to population to ecosystem. The second dimension is the diversity of all species in the biosphere. The third dimension is the history of each species in turn, comprising both its genetic evolution and the environmental change that drove the evolution. Biology, by growing in all three dimensions, is progressing toward unification and will continue to do so.
Take the crocodile, for example, my favorite animal. There are 23 species. Seventeen of those species are rare or endangered. They're on the way out, no matter what anyone does or says, you know.
Having studied biology really helped me a lot because I quickly understand how biological systems work, and how they fail, and the tragedy of when they fail, because we are dealing with life systems, and when we hear that a species has become extinct, or is threatened, you realize that this could mean that this species will disappear from the face of the earth forever! So that understanding really gives you energy to do something to save it.
Animals are, like us, endangered species on an endangered planet, and we are the ones who are endangering them, it, and ourselves. They are innocent sufferers in a hell of our making.
I think when you work on fossils, and you realize that a species is there, and it's abundant for quite a long period of time, and then at some point it's no longer there - and so, when you look at that bigger picture, yes, you realize that either you change and adapt, or, as a species, you go extinct.
Aside from bringing back extinct species, reanimation could help living ones by restoring lost genetic diversity. The Tasmanian devil (aka Sarcophilus harrisii) is so inbred at this point that most species members can exchange tumor cells without rejection.
That's the way to get young people. Once they see there are wonderful things to hunt for, to rediscover a species that was thought to be extinct or is extremely rare, to be the first to see a nest, to discover a new species unsuspected close to your home - these are things, I think, with a little education and excitement and the right kind of natural history would actually start a movement that makes going back to nature a profitable adventure.
When I was very young, biology, the diversity of life, was one of my main interests. I know there's this image people have that I'm this spoiled, cocky punk of an actor. Honestly, that's not who I am. I really care that so many species have been wiped out, like genocide of entire races. I believe in the divine right of all species to survive on this planet. So I decided I want to be active as an environmentalist. I learned. I asked experts. I got active.
In the 1970s, Safari Club International asked the federal government to approve its import of 1,125 not-yet-killed trophies of 40 endangered species, including gorillas, orangutans and tigers, according to the Humane Society of the United States.
'Extinction' issue. Save the species for whom??? Humans' convenience, of course! Individuals of the species are snatched from their homes/family/habitat/held in captivity/forced to mate at great physical/ spiritual pain. When the right numbers are reached, their holocaust starts all over again! Another merry-go-round/ bu$ine$$ a$ u$ual!!! Protectionists/welfarists find it a profitable issue: no controversy/ easy donations! I'd rather see an entire species extinct than in the hands of the humans!
We find all kinds of species that have taken up a second chromosome or a third one from somewhere, adding thousands of new traits in a second to that species. So, people who think of evolution as just one gene changing at a time have missed much of biology.
