In the past our country did not have computers, televisions,... they only games such as blindman's bluff, hide-and-seek. They are people who talk together. But now the teens are differnt from their time mostly on phones and computers. Now they text instead of talking. Play games instead of playing games as before. If so, the more they miss, the less they will stay away from society and not good for them

Marine pollution is a growing problem in today’s world. Our ocean is being flooded with two main types of pollution: chemicals and trash.
Chemical contamination, or nutrient pollution, is concerning for health, environmental, and economic reasons. This type of pollution occurs when human activities, notably the use of fertilizer on farms, lead to the runoff of chemicals into waterways that ultimately flow into the ocean. The increased concentration of chemicals, such as nitrogen and phosphorus, in the coastal ocean promotes the growth of algal blooms, which can be toxic to wildlife and harmful to humans. The negative effects on health and the environment caused by algal blooms hurt local fishing and tourism industries.
Marine trash encompasses all manufactured products—most of the plastic—that end up in the ocean. Littering, storm winds, and poor waste management all contribute to the accumulation of this debris, 80 percent of which comes from sources on land. Common types of marine debris include various plastic items like shopping bags and beverage bottles, along with cigarette butts, bottle caps, food wrappers, and fishing gear. Plastic waste is particularly problematic as a pollutant because it is so long-lasting. Plastic items can take hundreds of years to decompose.
This trash poses dangers to both humans and animals. Fish become tangled and injured in the debris, and some animals mistake items like plastic bags for food and eat them. Small organisms feed on tiny bits of broken-down plastic, called microplastic, and absorb the chemicals from the plastic into their tissues. Microplastics are less than five millimeters (0.2 inches) in diameter and have been detected in a range of marine species, including plankton and whales. When small organisms that consume microplastics are eaten by larger animals, the toxic chemicals then become part of their tissues. In this way, the microplastic pollution migrates up the food chain, eventually becoming part of the food that humans eat.
Solutions for marine pollution include prevention and cleanup. Disposable and single-use plastic is abundantly used in today’s society, from shopping bags to shipping packaging to plastic bottles. Changing society’s approach to plastic use will be a long and economically challenging process. Cleanup, in contrast, may be impossible for some items.
Nonetheless, many countries are taking action. According to a 2018 report from the United Nations, more than sixty countries have enacted regulations to limit or ban the use of disposable plastic items.

Road transportation is the dominant mode of transport for distances up to 500 miles. InEurope, some three quarters of freight is transported over roads. In the U.S. it is about two third similar to India. As this is not expected to change significantly in the future, road transportation will continue to play an important role in the future mix of the different modes of transportation.
As volumes are expected to grow, governments need to think about ways to deal with and plan for the additional freight.The objective should be a safe and secure, clean and fluid, as well as affordable transport system.
Self-driving vehicles will help in many ways to realize this vision on the roads: starting with absorbing additional volume without expanding the road system as autonomous vehicles drive closely together. They are also expected to be safer and more fuel-efficient. In addition, traffic flow will improve and congestion reduce. This means less investment, less fuel, less CO2 emissions, less time lost for driving and parking, and less accidents.

Nowday , everything is changing everyday after time and technology's development . It's more progressive , more modern and the transportation is too . Everytime , you go out in the street , you always see cars are moving everywhere . The transportation ' s industry invents and breaks the limit of speed and travel demand .

Or we will not have to pay for any charges of gasoline , that's a good change for us and a good new for enviroment . May be we don't have to move by any machine or motor anymore , we can go from Vietnam to London immediately by pressing a buttom . Don't you see , everything can be happen . The important is what you do today , to change the world .
P/s : There are so many mistakes of grammar and vocabulary , I expect that you can fix it for me .
