The problem of ecology is very important, because recently its quality is deteriorating, which means that all progressive humanity faces a huge danger, which will be very difficult to avoid, but first you need to think very well about your algorithm of action, as it depends on the solution of this complex and very important problem that concerns all mankind.
It is necessary to understand very clearly that all these problems that are related to the human environment concern each of us. All of us can not just stay away from these problems, as indifference can lead to very bad consequences. You need to start with yourself, as even a simple wrapper of candy can bring very great harm to the environment. Humanity, which simply and unceremoniously intervenes in nature, should stop and think about the consequences, but alone man with this problem is not right.
All the inhabitants of our planet, it is necessary to unite their efforts and try to change this situation, because later it may be too late to do anything. Starting from the earliest childhood, parents should carry out various educational work with their offspring, who should protect the world where they live, as this is a very important feature. What awaits humanity, which does not care about its environment? The answer is obvious: darkness and doom, but it can still be changed, but it just needs a little bit of effort, and then everything will be fine. We nature gives another, the latest chance, which we necessarily must use, so as more such not will, and as us to do, this to decide each of us, so, as only us given stop this technogenic lawlessness. The world must think and make the right choice.
