<span>Chemical pollution introduces chemicals into the natural environment, negatively affecting the air, water and soil. ... Toxic releases from industrial plants into the environment and agricultural runoff can threaten water supplies. </span><span>Many of the long-lasting effects of polluting the land, such as the leaching of chemicals into the soil, cannot be easily reversed. The best way to deal with land
pollution is to keep it from happening in the first place. Stepping up
recycling efforts and preventing overuse of soil that makes it acidic

The best and most correct answer among the choices provided by your question is the first choice.
The long-term effect if the trend continues would be: <span>Arteries and veins will fuse, causing oxygenated and deoxygenated blood to mix.</span>

1) they have similar chemical properties.
for example fluorine from the 17th column is a non metal so does all the elements of that group.
2)they have same valence electrons in their outermost shell
example
electronic configuration of
hydrogen 1, lithium 2,1, sodium 2,8,1 and so on.
3) have same valency.
Photosynthesis allows plants to take in sunlight, water, and carbon dioxide to make energy for themselves, a type of sugar called glucose.
Glucose =
The other thing that is made from photosynthesis is oxygen.
Without oxygen, we would not be able to live on earth.
Hope this helps!
