Indeed

I would not have survived my college world history class and 2 required psychology courses without crash course.

I graduated from high school way back in the pre-9/11 era, but I still watch these vids to help keep myself from getting stupider.

He did dedicate the first national monument, Devil's Tower... but yes you're right.

Teddy also had part in the start of the United States Forest Service

my boi you are damn right, didnt even pay attention to these

Hello dad

yeah same here :)

Go home Dad, you're drunk.

Considering you study English, that was not a very well formed sentence.

@@chloebutler8438 Amm that was informal writing. And I don't have to please you. That was me commenting on my favorite KZfaqrs' channel

Yes thank you!! I was just about to post that! It's a pity his name is largely forgotten these days even when he influenced so many others back in his day

yeeees, humboldt! he was amazing!

Right!! So disappointed to see he hasn't been mentioned once in this entire series!! :(

They can change other people's minds.

People who change their minds a lot tend not to accomplish much, either.

Historical ecology encompasses all of the data, techniques, and perspectives from paleoecology; land-use history from archival and documentary research; and long-term ecological research and monitoring extended over decades. Multiple, comparative histories from many locations can help evaluate both cultural and natural causes of variability and characterize the overall dynamic properties of ecosystems (Swetnam et al. 1999). In fact, twentieth-century trends suggest that disregarding history can be perilous. Examples include the emergence of increasingly severe wildfire activity in the western United States and the role of extreme drought in triggering forest dieback and accelerated soil erosion in the American Southwest. Human-generated changes must be constrained because nature has functional, historical, and evolutionary limits. Nature has a range of ways to be, but there is a limit to those ways, and, therefore, human changes must be within those limits. (Christensen et al. 1996) A primary objective of historical ecology is to help define the various limits, the natural range of variability for ecological systems (Swetnam et al. 1999). In this way, applying historical knowledge guides and constrains resource management actions to sustainably mesh with those limits. Environmental history research concentrates on the patterns and causes of ecological changes in the landscapes of these southwestern mountain ranges. It includes extensive work on historic, ground-based photographs for this area, with relocation and retaking of photographs that were taken as long ago as 1880 by the Bureau of Biological Survey, U.S. Geological Survey, USDA Forest Service, early archaeologists, and others.

These episode gives e brief information of ecology. How the nonliving and living things is related to each other. It also shows that in every actions of the living things have effects in the nonliving things. For me this episode is telling us that the knowledge we have about the ecology is must be applied to save our ecosystem.

Ecology is all about study of environment. It became a discipline while science continue studying life and the non-living things that affect life like water and soil. Vernadsky pioneered ways to analyse nature historically. One was the geochemistry, or using the methods of chemistry to understand minerals, another was biogeochemistry which analyses living and non-living processes. The3 scientist use experiments to generate mathematic models tracing the flow of energy from non-living source into primary producers, primary consumers, meat eaters and eaters of dead things. However, our environment is very important because it will contribute in the field of science like the living and non-living things.

Ecology is the study of the interactions of living organisms with their environment. Ecologists study within several biological levels of organization, which include organism, population, community, and ecosystem. I find this very essential to study since it seeks to explain the life process where in it is fact that we're included to it since I believe that everything is interconnected. What we do will be the product of what is happening right now.

Ecology by definition states that it involve studying the life and the nonliving things that affect life like soil and water. Answering why is it significant to us? Because it helps us understand how the world works. It provides useful evidence on the interdependence between people and the natural world, as well as the consequences of human activity on the environment. Here are some of the questions answered by British Ecological Society: Can we conserve a habitat and its biodiversity? Yes. Ecology provides the essential basis for nature conservation. Maintaining a mosaic of habitats ensures the survival of a rich variety of species. Can we predict the ecological effects of pollution and climate change? Governments and citizens around the world are increasingly aware of the consequences of atmospheric pollution and climate change. In large-scale experiments, plants and animals are exposed to carefully controlled atmospheres and different ecological conditions. Scientists use this information to understand how they respond to pollution levels, and make predictions about future climate change. Can we fish the ocean without depleting its riches? It is possible, but does depend on where we are in the world. In the Antarctic, the marine ecosystem is currently managed as a whole under an international agreement to conserve living resources. How does forest destruction affect bird populations? About one third of forest bird species cannot live in small remnants of forests. The smaller birds such as the forest robin will use patches as small as 10 ha and the largest species, such as the brown-cheeked hornbill, need patches bigger than 10 square km. Should mangroves be protected? Mangroves play a number of ecological roles from fixing sediments to acting as nursery site for young fish. Mangrove forests are also a source of food, medicine and firewood for local populations.

cough cough Vernatsky, of course I know that cough cough (I totally did not).

🤣

The climate is of a essential importance in ecology, but it's another thing. Ecology has its focus on how >living< things interact with each other and the enviroment.
