Answers

Answer:

O planting a tree belt  

Explanation:

A tree belt consists of a line where several trees are planted in a row, forming something like a fence. Like the fence, the plant belt aims to promote protection for an area that, for some reason, is fragile, like a dry and desertified land.

The best way to protect dry and desertified regions is with a vegetation cover, which can be done through the belt of trees. This vegetation cover will promote less impact on the region's soil, improve soil quality and prevent erosion, allowing the region to powerfully improve its geographic and environmental conditions.

He had created many things that made peoples lives easier. One of his inventions was a car that could operate on both water and land; this car was Batniks favorite. On water, it could float and travel at speeds up to 80 miles per hour. But on land, it could travel at speeds over 200 miles per hour. Batniks father had created this special car to help people from their island get to the mainland and other islands faster. When Batnik's father was a boy, the only method of travel from one island to another was by ferry, and the trip often took hours. People who were sick and needed medical help from the mainland would have to endure the long crossing or not go at all because of delays. Batniks father loved his homeland and wanted to ease the burden on the people, so he created the water car.When he showed the car to Batnik, Batniks father warned Batnik that the car should not be driven at the maximum speed on land or water because the engine could burst into flame. One day when his father was away, Batnik decided that he wanted to show the car to his friends. He drove it on the water, at first going only half the possible speed. Then, as his excitement grew, he increased his speed on the water and was nearing maximum speed. When he reached the land, he continued to accelerate. His exhilaration grew. Like the mythological Greek boy Icarus, who flew too close to the sun, Batnik forgot his fathers warning and pushed the gas pedal to the floor. When the car exceeded 200 miles per hour, it burst into flames.How is the character of Batnik's father in Too Fast similar to Pan in "Pan: God of the Wild"?Both act in ways that cause the deaths of young people.Both help people with new inventions.Both have aspects of joy and terror.Both travel throughout the world in unusual ways.
