Why are there so many dead trees in southern Ontario?
Most of southern Ontario’s old-growth forests were destroyed by logging, forest fires and settlement between the mid-1700s and the early 1900s. Loggers took the best pines and oaks to supply the European market. Many of the remaining forests burned in the accidental fires that swept through Ontario after the cuts.

Why are they cutting down all the trees?
Trees are cut down for timber, waiting to be transported and sold. Deforestation is the purposeful clearing of forested land. Throughout history and into modern times, forests have been razed to make space for agriculture and animal grazing, and to obtain wood for fuel, manufacturing, and construction.
What is killing pine trees in Ontario?

What is killing the ash trees in Ontario?
Emerald Ash Borer is a forest pest native to Asia that has killed millions of Ash trees in southwestern Ontario, and the Great Lakes States.
Are trees dying because of climate change?
Researchers found the death rates of tropical trees have doubled in the past 35 years as global warming increases the drying power of the atmosphere. Intact tropical rainforests are major stores of carbon, absorbing around 12% of human-caused carbon dioxide emissions.
Who can tell me why my trees are dying?

Is emerald ash borer still a threat?
UPDATE: As of late June, 2022, emerald ash borer has been found in Forest Grove, Oregon. This is the farthest west the insect has been found in North America.

Should you remove dead trees?
If your tree is dead or clearly dying, it’s a good idea to remove it. A dead tree is not just an eyesore, it’s a hazard (particularly in dense urban or suburban neighborhoods). We recommend having it cut down as soon as possible, especially if it’s near buildings or areas where people gather, walk, or drive.
What year will we run out of trees?
With the current rate of deforestation, the world’s rainforests will be gone by 2100.
Are more trees being cut down than planted?
Today, annual tree harvest vs. production on a worldwide scale shows that humans cut down approximately 15 billion trees a year and re-plant about 5 billion. That’s a net loss of 10 billion trees every year, and a rate that would mean the loss of all trees within the next 300 years.
Do we have more trees now than 50 years ago?
Earth today supports more than 3 trillion trees—eight times as many as we thought a decade ago. But that number is rapidly shrinking, according to a global tree survey released today. We are losing 15 billion trees a year to toilet paper, timber, farmland expansion, and other human needs.
What will happen if all the trees are cutdown?
With no trees, the land will heat up and dry out and the dead wood will inevitably result in enormous wildfires. This will fill the sky with soot that blocks out the Sun, causing failed harvests for several years and leading to worldwide famine.
What will happen if all the trees will be cut down?
The soil would become full of dangerous chemicals and pollutants that are usually filtered by trees. In addition, soil erosion is currently prevented by trees because they protect the land. However, soil would be unprotected, and vulnerable to reduction in soil quality and top soil nutrients.
