Short and Long Term Changes

ENVIRONMENTAL CHALLENGES WORLDWIDE.

Environmental problems

Multiple Choice

Which of the following is not an abiotic factor?

• sun
• temperature
• soil
• grass

Learning Objective:

• We will explore how short-and-long-term environmental changes effect organisms and traits in subsequent populations.

Multiple Select

If we plant trees, ...

• we will fight deforestation.

• we will help endangered species.

• we will reduce air pollution.

• we will increase radioactive contamination.

Short Term Changes

• Changes that occur quickly in an ecosystem and affect organisms immediately.

• Does not give organisms time to adapt to changes.

• Forces populations to move or possibly risk death.

Poll

What do you think is an example of Short Term Environmental Change?

• Drought

• Flood

• Volcanic Eruption

Multiple Select

When we create conservation programmes...

• species are protected.

• new trees are planted.

• the soil is contaminated.

• water is consumed properly.

How Do Short Term Changes Affect Organisms?

• Drought – the severe lack of rainfall causes producers to die which eventually reduces food sources for all other organisms.

• Flood – organisms that are unable to escape the rising water are swept away and drown.

• Volcanic eruption – gas, ash, and lava covers a large area and destroys shelters, food sources,  and habitats of many organisms.

• Globalization reaches the natural environment since many of the environmental problems are global in scope and of general concern. For this reason, for several decades, different governments, environmental groups, and other sectors of society have been proposing alternatives to environmental problems of a global nature.

EVOLUTION

Multiple Choice

Change over time is

• evolution
• generation
• growth
• biogenesis

Multiple Choice

One of the consequences of the high levels of carbon dioxide into the atmosphere is:

• The contamination of the continental waters.

• The global warming.

• The decrease of the greenhouse gas emissions.

• The deforestation.

Fill in the Blanks

• The decrease in the number and variety of animal and plant species in the different continents, as a result of economic development processes not consistent with the care and protection of the environment. 

• The loss of the productive capacity of the soils, due, to a great extent, to intensive agricultural practices that do not allow an adequate regeneration of the soil. Much of the production of toxic waste, as well as its transport and final disposal of large industries, influence this problem by altering the composition of the soil to the point of desertification.
