Which human activity has the lowest effect on global stability?

(Choice A)

Removing carnivores from a forest

(Choice B)

Heating homes with fossil fuels

(Choice C)

Reusing plastic bags

(Choice D)

Adding heavy metals to the water supply

I think the answer is C

''Reusing plastic bags''

Explanation:

Removing carnivores from a forest  has a great impact on a environment since the population of the herbivores will increases drastically and the dynamic equilibrium of the area will be greatly effected.

If we look at choice B '' Heating homes with fossil fuels'', this will also have a big impact on the earth since fossil fuels are non-renewable and take centuries to form. Heating homes with them will result in loss of fossil fuels.

Now let's look at choice D ''Adding heavy metals to the water supply''. Heavy metals are dangerous to the human health and even cause cancer. This will cause thousands of deaths and will also have a great impact on the global stability.

This leaves choice C ''Reusing plastic bags''. This will cause less pollution and less harm to wildlife but doesn't have any big threat to the global stability. As in changing the world population or causing deaths in large numbers.

so I think choice C is the answer

b is dominant over the allele for the white fur.

if you add everything up correctly you should get 69 i got this because 50 plus 19 is it
