what be the definition for sustainability that come in environment? I find that it be meeting the needs of the present without compromising the ability of future generations to meet their needs. but i not real understand what this means

Answer 1

We need fuel such as gas and oil. But someday the earth's supply of gas and oil will be gone. Sustainability means to ind other fuels that we can reproduce. For instance, we can sustain our woodlands by planting more trees when we cut down some of them. Sustainability in agriculture is to follow good farming practices such as rotating crops and letting fields lie fallow sometimes.
