Scientists suggesting that the Earth may be on the verge of the next possible mass extinction, but that this time, we may be to prevent it.
The main cause for this direction is human's selfish activities like over harvesting the sea, and environmental issues that threw many of natural cycles into disarray, causing drastic climate changes like long drought etc. The "water war" like in science fiction will be real issue in near future.
“So far if you analysed the last few hundred years of life on the earth, human activity had apparently wiped out 1.4 % of all plants and animals species, and its hundred and a thousand times faster than normal because of human population, of development, pollution, over harvesting and if you take a look at zoo, many zoo animals that our children loved we may find them going extinct, the tiger for example may go extinct, many familiar zoo animals, bears, and realized that 18,000 species are at risk.” Dr Michio Kaku, Physic s Professor of City University of New York; author of “Physics of the future”.
In Buddha's teachings, since the beginning, we are asked not to harm other sentient beings and not to destroy plants. Buddha spelled them out as vows of for monks and nuns.
Human need to learn to live in harmony with other species and be less greedy for our own selfish gains.
