His little sister is coughing, the sky often looks grey, and a strange<br \/>\nsmell lingers near their school. When Kojo and his friends \u2014Amina, Yaw, Esi and Sule \u2014 begin asking questions, they uncover a problem many adults have ignored: the air is becoming unhealthy. Their journey takes them from Tema&#8217;s fishing harbour to the streets of Accra, and even to the quieter towns of Aburi and Koforidua. Along the way they face dangers, difficult choices and doubts about whether children can really make a difference. Choosing Clean Air in Tema is an inspiring<br \/>\nstory about courage, responsibility and hope, showing that even small voices can help clear the air for a better tomorrow.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In the busy coastal city of Tema, ships arrive and markets buzz, but&hellip;<\/p>\n","protected":false},"featured_media":2132,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[234,228,214,223,225,227,233,222],"product_tag":[],"class_list":["post-2131","product","type-product","status-publish","has-post-thumbnail","product_cat-african","product_cat-primary-schools-books","product_cat-sdg-novels","product_cat-social-and-current-issues-books","product_cat-solutions-to-personal-national-and-international-problems-and-challenges-books","product_cat-student-story-books","product_cat-sustainable-development-goals-1-17-books-for-all-countries","product_cat-s-d-g","first","instock","sale","taxable","shipping-taxable","purchasable","product-type-simple"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.4 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>- Calculus Series &amp;
