Yesterday,we didn't have today we erday,we didn't have TV today we erday we didn't have today we ng the hundreds of years,how fast the world has changed!That's really a myth.
Though the new world brings us a convenient also brings more example,population,resources ,environment and so on.
We know that the world's population is growing faster and faster. It's more than 6 billion 's a very big can say the number of world's population is like the number of the stars in the if it goes on like that,I can't image what will happen.
As the second problem,the world is short of resources daily life,we need water,rock oil,coal and other after day,the resources disappear they won't use most of them are not renewable resources.
The third problem is yone talks about weather is hotter and hotter means we pollute the environment cars make the air batteries make the soil e water makes clean water we don't have fresh air,fecund soil and pure , polluting!
