Because gm crops can't replace everything. yes even they can make a better species and increase the productivity, but some countries or farmers might not have the technology to replace all the crops with gm crops, and they still have to rely on chemical fertilisers. chemical fertilisers can be deadly as if u overuse them, it can pollute the water and leading to euthrophication, where it can kill sea animals
The grassy plains made up the majority of the fertile crescent. Although this region was suitable for farming, it lacked materials like stone, wood, and metal. Knives, spears, weapons, constructing buildings or shelters, and creating fires were only a few of the challenges these shortages brought on for the locals.
Plant and animal cultivation is known as agriculture or farming. Farming of domesticated species produced food surpluses that allowed people to dwell in cities, and this was the crucial innovation in the birth of sedentary human civilization.
Farming has a long history dating back a very long time. Around 11,500 years ago, early farmers started to sow the wild grains they had been harvesting for at least 105,000 years. Domestication of pigs, sheep, and cattle dates back more than 10,000 years. Despite the fact that 2 billion people still relied on subsistence agriculture in the 20th century, industrial agriculture based on massive monocultures began to dominate agricultural production.

The heaviest elements settled in the Earth's center during the formation of Earth's lithosphere
<u>Explanation:</u>
Earth's lithosphere comprises the crust and the uppermost mantle, which form the strong and rigid external layer of the Earth.
The Earth, on the other hand, begins with a core of iron and radioactive materials such as uranium and plutonium, which deliver energy in the form of heat, within a process known as nuclear fission. It passed by a fusion stage - a "liquid-pasty" state - which provided that, due to gravity, the more solid materials dropped towards the center, while the smaller ones floated towards the crust, a process called planetary differentiation.
