World Day of Social Justice
February 20, 2020

World Day of Social Justice was initiated by the General Assembly of the United Nations in 2007 to encourage support for international efforts in poverty eradication, the promotion of full employment, gender equity and justice for all. This year’s theme “Closing the Inequalities Gap to Achieve Social Justice” provides students and teachers with an excellent opportunity to focus attention the issue of fair employment along with the other barriers to social well-being that millions of people face because of gender, age, race, ethnicity, religion, culture or disability.

Why Care About Social Justice:

o By 2019, more than 212 million people were out of work, up from 201 million in previous years. (UN)

o Over 1.5 million children under the age of 5 die each year from vaccine-preventable diseases. (WHO)

o There are currently 800 million people who do not have access to safe drinking water. (UNESCO)

o Armed forces in 20 countries are recruiting child soldiers under the age of 18. (Child Soldiers International)

o The tuberculosis rate among Canada’s First Nations ranges from 10 to 30 times higher than that of the population as a whole. (CBC)

o Eighty-two million girls now aged 10 to 17 will be married before their 18th birthday (UNFP).

o One hundred million more women would be alive today if females had equal access to nutrition and health care. (WHO)

o Of the 4.5 million refugees forced to flee Syria, over one million are children. (UNHRC)

o The gap between rich and poor within and among nations continues to grow and promote conflict.

o Social justice is an underlying principle for peaceful and prosperous coexistence within and among nations

o A sustainable future involves meeting the needs of all people.

World Water Day:
March 22nd, 2020

World Water Day was conceived during the United Nations Conference on Environment and Development held in Rio de Janeiro in 1992. Since then the goal of the annual celebration has been to draw international attention to the need for sustainable management of this vital resource. Each year World Water Day places attention on a different aspect of freshwater. This year’s theme, “Water and Climate Change” will focus attention how global climate change is impacting the availability, quality and sustainability of fresh water.

World Water Day 2020 provides teachers and students with excellent opportunities to explore the role of water in sustaining life, to understand its inextricable connection to climate change and to become involved in water and climate change issues within their own communities.

Why Care about World Water Day? 

• Clean, freshwater is a basic requirement for all life

• While 70% of the earth’s surface is covered with water, less than .003% of this water is potable.

• Today, > 2.1 billion people live without access to safe drinking water. (UN Water, 2018)

• Everyday women spend >200 million hours carrying water

• Canada ranks second in the world in per capita use of water (Conference Board of Canada, 2018)

• For many of the 400,000 Canadians living on First Nations reserves, access to safe drinking water remains a major challenge

• Water is an integral part of the earth’s web of ecosystems, providing critical habitat for wildlife.

• Canadians depend on healthy aquatic ecosystems to provide essential economic and social services

• The earth’s fresh water resources are facing increasing threats related to climate change (UN Water, 2019)

• Extreme weather events are making water more scarce, more unpredictable and more polluted.

• Currently, a growing demand for water is increasing the need for energy-intensive practices (pumping, transportation & treatment) that contribute to global warming.
