Three main resources necessary for human survival are air, food, and water.
Near necessary resources.
Survival
amino group and carboxylic group
survival
There are very few if any positive effects, because human beings are not necessary for the maintenance/survival of the ecosystem. The most we can do is minimize our negative effects.

They do not. While gold is sought after for its value and rarity, it is not necessary for life/ survival.

amino group and carboxylic group
In general humans are making survival more difficult for elephants. However, some humans are tyring to make it easier.
There are some natural sources of water available. Three of them are lakes, water tanks, and springs. Water is necessary for the survival of both humans and animals.
survival
economically important resources are those which have humans heavily rely on and cannot live without. One example is coal. Without coal around 75% of electricity generation in the world wouldn't be possible. Same goes for oil, like oil can be broken down into many forms to produce things like vaseline, petrol which humans depend on everyday basis.They are basically resources which have to have alot of importance for survival for humans and they arent cheap.
If there is no reproduction the species will end when those now existing die. If humans stopped reproducing today. Our species would end when the last of us dies.
