The story is commonly recognized as a fable concerning the danger of greed causing human destruction of the natural environment, using the literary element of personification to create relatable characters for industry (the Once-ler), the environment (the Truffula trees) and environmental activism (the Lorax). The story encourages activism and ...
The more trees that are removed equals larger effects of climate change which, in turn, results in the loss of more trees. [13] Forests cover 31% of the land area on Earth. Every year, 75,700 square kilometers (18.7 million acres) of the forest is lost. [14] There was a 12% increase in the loss of primary tropical forests from 2019 to 2020. [15]
As a result, the presence or absence of trees can change the quantity of water on the surface, in the soil or groundwater, or in the atmosphere. This in turn changes erosion rates and the availability of water for either ecosystem functions or human services. Deforestation on lowland plains moves cloud formation and rainfall to higher elevations.
The island of Hispaniola was first colonized by humans 6,000 years ago and the population size was likely more than one million when the European colonists first arrived in 1492. [6] Those original inhabitants used trees and caused extinctions of birds and mammals. [11] [12] Nonetheless, the greatest deforestation occurred after 1492. [8]
Small ponds may experience shading by surrounding trees, while cloud cover may affect light availability in all systems, regardless of size. Seasonal and diurnal considerations also play a role in light availability because the shallower the angle at which light strikes water, the more light is lost by reflection.
The technical distinction between a pond and a lake has not been universally standardized. Limnologists and freshwater biologists have proposed formal definitions for pond, in part to include 'bodies of water where light penetrates to the bottom of the waterbody', 'bodies of water shallow enough for rooted water plants to grow throughout', and 'bodies of water which lack wave action on the ...

Humans had a very early contact with the sentient moon Erythro, a very abstract alien intelligence. In Foundation's Triumph, the last book in the Second Foundation Trilogy (authorized by Asimov's estate), another possible future for the Galaxy is discussed. In a conversation between Hari Seldon and Daneel Olivaw, Seldon discusses the ...
