Answer:
People have to earn a living, and we only have one world to share. When a farmer plants his crop, he kills any bugs, molds, or rodents that might destroy the plants. If there is a law against that, then either the farmer commits a crime, or he can't support his family and has to collect welfare. Either way, he stops paying taxes. A government can not stand when the people don't pay taxes.
We already have laws in the USA that make a farmer liable if a protected species of duck eats a protected species of bug on his property. The only reason that is possible is that everybody ignores the law. So there is no point in having the law. Somehow, everybody fails to see why this is a stupid way to run a country.

The relationship between environment, variation and selection lay the foundation for natural selection and evolution.
Genetic variations are present among species due to number of reasons like recombination or crossing over during meiosis, mutations, random fertilization etc. These factors bring changes among the members of a species. Some of the species become better adapted to survive in a particular environment whereas some are not better adapted and become extinct over a period of time. The environment selects the organisms that are best adapted to survive and hence lead to variations.
