There could be different answers towards this question depending on how you view the current situation. This is my opinion towards the answer.
Yes, the world currently is over populated as the Earth cannot produce enough resources to sustain human activity in the future hundred years. According to researches, approximately 3.1 Earths will be needed to provide sufficient resources for the most developed city.
Currently, there are 7.5 billion people living on Earth and some places are already facing problems of the lack of natural resources like water and food, and have to rely on import to sustain civilians lives. This is often the result of the exhaustion of resources such as overcultivation to satisfy the need of such large population. We can therefore see that the world is indeed overpopulated.
Hope it helps!
Answer:
D.) Cold treeless lands
Explanation:
Canada is the second largest country in the world. It occupies slightly less than half of North America. The country is located on a high latitude though, so its climate conditions are not the best, as the country in general is very cold.
The northern 40% of the country though are even colder than the rest of the country. This part of Canada falls into the tundra biome. It is area where the winter dominates for most of the year. The summer is not summer in the real sense of the world, as it is very short and relatively cold as well. The temperatures in this part of Canada are very low. The landscape is covered with ice and snow for most of the year, and there are strong, cold, dry winds.
Because the climate conditions are like this, this part of the country doesn't have trees. Instead, in the short ''summer'', the plants that dominate are very small ones that don't require much to survive. The plants that manage to survive in these conditions are mostly mosses, lichens, dwarf shrubs, and algae.

Yes, wikipedia says "</span><span>It can be used to </span>date<span> rocks that formed and crystallised from about 1 million years to over 4.5 billion years ago with routine precisions in the 0.1–1 percent range.</span>"
Therefore, 250,000 years can be compared
